AUTOMATIC CARBONATING SIPHON BOTTLE Original Filed Sept. 13, 1937 Patented Sept. 26, 1939 UNITED STATES PAENT OFFICE AUTOMATIC CARBONATING SIPHON BOTTLE ration of California Application September 13, 1937, Serial No. 163,693 Renewed February 18, 1939 7 Claims.

This invention relates to and has for an object the provision of a simplified Vand otherwise improved carbonating Siphon bottle of the type forming the subject matter of my application for patent, Serial Number 159,613, led August 17, 1937, wherein a combined carbonating and liquid and gals intaking means mounted within a Siphon bottle provides for a thorough carbonating action by saturating the liquid with the gas within the bottle during the intaking of the liquid and gas.

In. the combined carbonator and siphon bottle of my aforesaid application the Siphon bottle is equipped with the usual valved dispensing head and a combined carbonating and intaking means, which latter includes aV movable liquid discharge tube extending upwardly into the bottle from the bottom thereof. The lower end of the tube is equipp-ed with a liquid intake valve which is opened by pressure of liquid discharging into the tube from a filling fountain, Lsaid tube being engaged with the fountain soy that the valve of the fountain is thereby opened and the tube is moved upwardly whereby such upward movement will open the gas intake valve in the bottle and ther-eby allow the gas to enter said bottle. Upon disengaging the tube from the lling fountain the liquid intake valve, constructed as an outwardly closing check, will automatically close and the tube in being spring loaded, will move back to normal position and thereby close the gas intake valve, the pressure within the bottle holding said valve tightly cldsed.

An object of the present invention is to provide a carbonating bottle of the character described, wherein the liquid intake tube carried by the bottle, is fixed instead of being movable and the intaking of liquid and gas is effected through outwardly opening check valves carried within the bottle, both of which open when the lower end of the tube exposed at the bottom of the bottle is engaged with a filling fountain and liquid and gas under pressure are discharged from said fountain against said valves. In this form the valvm will automatically close when the bottle is disengaged from the fountain.

A further obj-ect of this invention is to provide an automatic carbonating siphon bottle which, together with a filling fountain that may be conveniently located upon a service bar, kitchen shelf or within a refrigerator and connected with sources of supply of liquid and gas under pressure, makes possible an eiiicacious charging of the bottle with gas and liquid and an automatic carbonating of such components` at the time of the discharge thereof into the bottle,

through the simple expediency of placing the bottle against or upon the filling fountain and allowing it to remain until the bottle is fully charged, said bottle being readily removable from the fountain at will, in order to dispense the carbonating liquid as desired.

I have shown in the accompanying drawing a preferred form of an automatic carbonating siphon bottle embodying my invention, subject, however, to modification, within the scope of the appended claims, without departing from the Spirit of my invention.

Referring to the drawing:

Fig. 1 represents a fragmentary vertical sectional view of the automatic carbonating siphon bottle of this invention as when connected with the filling fountain which is likewise Shown in vertical section,

Fig. 2 represents a vertical sectional view of the filling fountain as when closed, and

Fig. 3 represents a fragmentary side elevation of the bottle and fountain as when connected.

One embodiment of the automatic carbonating Siphon bottle of this invention as shown inthe accompanying drawing, comprises the siphon bottle 4 equipped with the usual siphoning or dispensing head 5 and an automatic carbonating and intaking means Ii, which latter is adapted to 'oe engaged with a fixed filling fountain 'I. As here shown this fountain may be mounted upon a shelf, serving bar or like support 8, or fixed within a refrigerator and connected by pipe lines 9 and I0 with sources of supply of gas and liquid under pressure, not lshown. The gas supply line 9 may be equipped with a Suitable control valve I l and a pressure indicator I2, whereas a suitable valve I3 will control the liquid feed to the fountain. The discharge of gas and liquid from the fountain is controlled by valve means I4 in the form of a tubular stem I5 vertically movable in a bore I5 in the body Il of the fountain. At its upper end this bore is provided with a discharge opening I8 formed o-n its low-er side with a valve Seat I 9 for an annular valve 20 xed on the periphery of the tube I5. The valve ils normally held closed by means of a spring 2l and is opened when the tube I5 is depressed against the action of said spring. The gas line 9 is connected by means of a fitting 22 with the side of the body I'I so as to discharge through a passage 23 into the bore I5. Thils passage is controlled by a check valve 24 which opens responsive to the line pressure of the gas when the valve II is opened. At its lower end the body I'I is provided with a chamber 25 into which liquid is discharged from Cil the pipe I through a passage 2B in a plug 21 to which the line Ii) is connected. A Valve 28 is normally held closed by a spring 29 to prevent the entrance of liquid from the chamber 25 into the lower end of the tube I5. When this tube is deprelssed it engages and opens the valve 2B and liquid will now from the chamber 25 around the valve and into the tube through lateral intake openings 3l) in the latter, as particularly shown in Fig. l. The liquid will pass upwardly through the tube l5 and out through the upper end thereof, which latter extends through the opening I8 so as to leave a space around the tube sufcient for the discharge of gas from the bore I6. This upper end of the tube I5 is disposed in the center of a female coupling 3i secured to the body I1, extending above the shelf 8. This coupling member is provided with interrupted internal screw threads 32 that will as hereinafter described, provide for a quick-detachable connection of the siphon bottle with the fountain.

In accordance with the present invention the carbonating means is constructed so as to be comparatively light and to consist of a minimum number of parts, especially moving parts, the only moving parts necessary being the simple elements of two check valves as will be hereinafter eX- plained. This means 6 comprises a plug-like body member 33 which is screwed into a ring 34 fixed upon an upstanding annular flange 35 formed at the margin of an opening 35 in the bottom 31 of the bottle. The ring 36 is welded or otherwise secured to the flange so as to form a permanent and tight seal. The plug-like body 33 has its lower end formed as a tubular male coupling e tended so that it may be engaged in the coupling 3l and connected therewith by means of external screw threads 39 thereon. An annular groove d@ in the plug 33 receives the coupling 3l as indicated in Fig. l, and may be provided with a cushioning washer or packing ring di. it will be noted that the lower end of the coupling 39 is disposed slightly above the plane of the lower end of the bottle, the bottom 31 of the bottle being concaved to accommodate this arrangement and to prevent contact of the coupling 38 with the surface upon which the bottle is rested.

When the siphon bottle is coupled with the fountain as shown in Fig. l, the upper end of the tube l5 of the fountain will engage a cornpressible ring 62 fixed upon a boss 43 carried by the plug 33. This will depress the tube I5 so as to open the valves 29 and 28, thereby allowing gas and liquid to be discharged by the fountain. The liquid discharging from the tube I5 will enter a passage d through the boss 43 and open a check valve '35 mounted in an enlargement 46 of said passage, the pressure of the liquid opening said valve. From this enlarged portion 45 the liquid passes upwardly through a tube 41 fixed to the plug body said tube having an atomized 48 at its upper end which is disposed adjacent the upper end of the bottle. lThis atomized will cause the liquid to be discharged into the bottle as a fine whirling mist or spray.

The gas from the fountain discharges around the tube lil into the interior of the coupling 38 and from thence flows through an intake passage 4S. A check Valve 55 normally closing the passage 49 is opened by the pressure of the gas and permits the gas to discharge through a nozzle 5I mounted in the plug body 33. This nozzle is comparatively small so that the gas enters adjacent the lower end of the body and upon rising therein,

will thoroughly saturate the ne mist or spray of liquid discharging from the atomizer. In this manner the carbonating action takes place at the time that the gas and liquid are introduced, the gas entirely saturating the ne mist of liquid discharging from the atomizer and also by rising through the body of carbonated liquid which c01- lects in the bottle.

It will now be seen that the check valves 45 and 5i) control the admission of liquid and gas into the bottle and are opened by the pressure of liquid and gas streams discharging from the fountain. When the bottle is detached from the fountain these valves will automatically close and be held in such position to prevent leakage by the pressure built up within the bottle.

It is now seen that it is only necessary when the bottle is to be refilled and the liquid and gas are thereby carbonated while being introduced into the bottle, to place the bottle upon the fountain and give it a slight turn so as to engage the screw threads 32 and 39 of the coupling members 3l and 38 respectively. This connection will provide at the same time for the openings of the valves Z and 23 in the fountain, due to the depression of the tube I5 and when these valves 20 and 23 are open, the pressure of the gas and liquid will be applied from the fountain against the valves d and 45 respectively, carried by the bottie, whereupon the gas and liquid will be charged into the bottle and the carbonating action hereinbefore described will take place within the bottle during the charging thereof with said gas and liquid. After the bottle has been charged it may be turned slightly, whereby to disengage it from the fountain and then may be removed and used in the ordinary manner to dispense a thoroughly carbonated liquid by manipulation of the Siphon head 5 as desired. It is important to note that the bottle is extremely light and consists of comparatively few parts and may be quickly and easily charged as desired, through the provision of this invention, in a most convenient manner. When the fountain is installed, forl instance in a refrigerator, the bottle may be connected with a fountain and allowed to remain thus connected until the use of the bottle is required, whereupon but a slight turning movement is necessary to disengage the bottle from the fountain and an entirely charged carbonated liquid may then be dispensed in the ordinary manner.
